What rpm stall converter should use?

I’m asking so many questions because I’ve been away from Mopar for about 32 years. The Last Mopar I bought before this one was one I bought from GTX John in 1984,it was a Bob Lambeck prepared C/stock road runner 440 6-pack 4 speed car that I used to street race, and Occasionally take to the strip.
No need to justify. You're doin the right thing. Too many people on here just forge ahead and never listen. Not that you certainly cannot build whatever you want your way, but you'll see a pattern on here of people asking for advice, getting good sound advice from a group with over 100 years collective experience and turning around and doing the exact opposite. lol
